TCP

Command

TCP -- TCP status / configuration commands.

Synopsis

TCP <L[isteners] | R[eset] sock# [sock#] ...| S[tatus]>

Availability

Sysop-only.

Description

The TCP command is used to display various parameters of the TCP module, and to reset connections.

Options

"TCP L[isteners]" displays the IP addresses and TCP port numbers for the listener (server) sockets. An IP address of 0.0.0.0 indicates that the socket is listening on all XRPi's IP addresses.

"TCP R[eset] <sock#> is used to reset (close) the connection(s) whose socket number(s) are specified by <sock#>. This would typically be used to close malicious or "stuck" connections. The socket number(s) may be obtained by the STATUS subcommand.

"TCP S[tatus]" displays the status of all the current TCP connections.

The display shows the socket number, the remote and local addresses, the state, and the amount of queued data in bytes. The states are as follows (see RFC793):

	0    Closed              6    FINWAIT2
	1    Listen              7    Close wait
	2    SYN sent            8    Closing
	3    SYN Received        9    Last ACK
	4    Established         10   Time Wait
	5    FINWAIT1
